MADISON, Wis. (AP) -- True to his word, a Wisconsin hermit who encased his dead mother in a block of ice keeps to himself in solitary confinement.

When Philip Schuth was sentenced to prison in 2005, the 56-year-old said he feared other inmates and wanted to live in solitary confinement. Records show he's been doing that, earning more than 1,400 days in solitary for disciplinary issues.

Schuth lived for decades with his mother near La Crosse. Four years ago a man approached Schuth asking if he had hit the man's son. Schuth shot the man and retreated into his home.

Officers who investigated found the body of Schuth's mother encased in ice in a basement freezer.

Schuth's lawyer says his client's bizarre prison behavior shows why prison isn't a good place for people with mental illness.
